The answer to 'my installation keeps shutting off' is that there are several common causes, including issues with the thermostat, electrical problems, refrigerant leaks, or a malfunctioning component. Symptoms may include the system turning on and off repeatedly, inconsistent temperatures, or reduced airflow. Solutions can range from simple adjustments to more complex repairs, depending on the root cause.
If the issue is something simple like a thermostat or wiring problem, you may be able to troubleshoot and fix it yourself. However, for more complex problems involving refrigerant, electrical systems, or major components, it's best to call in a professional HVAC technician. They have the expertise and tools to properly diagnose and repair the issue to get your system running reliably again.
